+ | One of the limitations of the charge pump is the impossibility to obtain larger supply currents. The problem can be solved using a transformer and electronic circuit, which convert the input DC voltage to AC. Given that the converted voltage can be of significantly higher frequency than the usual 50 Hz, thus the size of the transformer, | ||
+ | |||
+ | Moreover, in the case of input DC potential commuting sinusoidally on the transformer windings, the possibility of noise emission is considerably decreased compared to the conventional SMPS. | ||
+ | |||
+ | Another advantage in using the transformer is, that the output power supply can be galvanically isolated from the input power supply. | ||
